A facile template approach for the synthesis of mesoporous Fe3C/Fe-N-doped carbon catalysts for efficient and durable oxygen reduction reaction

Layer-structured FeOCl was used as a novel inorganic template and the Fe doping source for the facile synthesis of three-dimensional polypyrrole structures which can be converted into mesoporous Fe3C/Fe-N-doped carbon catalysts for efficient and robust oxygen reduction reaction.
